In this second part of my paper, for closed Universes of General Relativity, a «two-event» energy-momentum tensor density and a «two-event» superpotential are defined. In this way it is possible to define the total «four momentum» as a vector and to put the conservation laws (the local and global ones), in covariant form. Both the «two-event» energy momentum tensor density and the superpotential coincide with Einstein's energy momentum complex and with Freud's superpotential in a particular class of coordinate systems.
